MACHINE FOR DIPPING CONFECTIONERY AND THE LIKE.

Specification of Letters Patent.

Patented March 16, 1909.

Application filed October 31, 1908. Serial No. 460,376.

2 machine that is adapted to facilitate the dipping or coating of biscuits, cakes and eonfections, or, in other words, to facilitate the coating of said cakes, etc., with chocolate or 1 other confection of a similar nature, by dipping the said cakes wholly or partially into the molten confection; for instance, if I desire to put a small amount of chocolate on top of biscuits having marshmallows thereon, I place the biscuits in the machine and cause the tops or sides thereof to be dipped into molten chocolate, whereby the chocolate will adhere to the marshmallows or biscuits.

My improved machine is adapted to treat any kind of cake or confection, and any coating material, other than chocolate, can be used.

To carry out the object of my invention, I employ means whereby the coating material can be kept in a molten condition while the machine is in operation, or even if the machine is idle.

Other special features of improvement will appear throughout the specification, such as special means for retaining cakes and means cooperating with the retaining means to successfully carry out the cycle of operations.

I will now proceed to describe my invention in detail, the novel features of whichI will finally claim, reference being had to the accompanying drawings, forming part here of, wherein:-

Figure 1 is a front elevation of my improved machine, partly in section, the section being taken on a line aa in Fig. 3; Fig. 2 is a fragmentary sectional longitudinal view on a reduced scale of the top portion of my machine, the section being taken on a line b'?) in Fig. 1; Fig. 3 is a top plan view 55 of my improved machine, on a reduced scale,

the top shelf being broken away, as shown; Fig. 4 is an enlarged detail sectional view of the clutch which controls the operation of my machine, the section being taken on a line cc in Fig. 5; Fig. 5 is a longitudinal sectional plan view, the section being taken on a line dd in Fig. 4; Fig. 6 is a fragmentary plan view of one form of a cake retaining frame, employed in my machine; Fig. 7 is an enlarged sectional view thereof, the sections being taken on a line c@ in Fig. 6; Fig. 8 is a fragmentary plan view of another form of cake retaining frame Fig. 9 is a front view of a hand-operated machine, broken away as shown, embodying my improvements; and Fig. 10 is a central longitudinal sectional view thereof.

Referring now to the drawings, particularly to Fig. 1 m improved machine comprises frame mem ers 1 which are bound together by a brace 2.

One of the special features of my machine comprises a reservoir 3, which is carried by the frame members 1, the said reservoir being composed of an inner case 4 and an outer case 5, the said casings being separated to form a chamber 6 into which a heating medium, such as steam or hot water, can be introduced. The said medium can be introduced into the chamber 6 through a pipe 7 and drawn off through an exhaust pipe 8. The reservoir 3 is designed to retain a confection, such as chocolate or similar substance, in a molten condition, the said substance being indicated by 9. To get the best results, the substance 9 must be kept in a molten condition, at a certain temperature, in order that the said substance will flow evenly and adhere to the articles dipped therein. To get this result, I construct the reservoir 3, as above mentioned, and intro duce a heating medium under and around the inner case 4, which contains the substance 9, the said heating medium being adapted to keep the substance in the said molten condition.

Instead of dipping the articles directly into the substance 9, I employ a subsidiary receptacle 10, which is situated within the reservoir 3, in this instance, and adapted to be submerged in the substance 9 and filled, at intervals, with the said substance, as indicated by 11. When the receptacle 10 has been withdrawn from the molten substance,

the said receptacle will be filled flush with the top thereof as shown. To adapt the re ceptacle 10 for a vertical or reciprocating movement, I mount the. said receptacle upon rods 12 (Figs. 1 and 2) which are slidably carried by the side rails 13 of a frame 14 (see Fig. 3), the said frame being pivotally mounted on a rod 15 and adapted for movement longitudinally thereof. The rod 15 is carried by the frame member 1 as shown. Each pair of rods 12 on each rail 13 is connected by a bar 16 (see Fig. 2), springs 17 being interposed between the bars 16 and rails 13 for the purpose of withdrawing the receptacle from the molten material 'after the said receptacle has been submerged. To adjust thereceptacle 10 relative .to the cake retaining tray, I employ adjusting screws 18, which are adapted to bear against the said receptacle as shown in Fig. 2. The position of the receptacle relative to the tray is dependent upon the height of the articles to be. dipped, also upon the extent to which the articles are to be dipped.

Adjacent to the receptacle 10, and upon the rails 13, I slidably mount tray-carriers 19, the said carriers being provided with a slot 20, through which a screw 21 passes, the said screws being adapted to slidably retain the carriers in position, as shown. The carriers 19 are held in alinement by means of studs 22 (Fig. 1), around which a spring 23 is wound. The springs 23 act to restore the tray-carriers 19 after each depression thereof.

Each pair of tray-carriers 19 are connected by an angle iron 24, the said angle iron serving as a retainer for a tray 25, the said tray being adapted to contain cakes 26. The tray 25 is removably supported by the said angle irons 24.

Various forms of trays can be used, but I have herein illustrated a form of tray com-. prising end members 27 and a central member 28 (see Figs. 7 and 8). The central member 28 is provided with sockets 29, 29*, which are formed by battens 30. The cakes 26 are placed within the sockets 29, 29 as shown in Fig. 7. The sockets 29 are larger than the sockets 29 in order to accommodate larger cakes. In Fig. 1, the sockets 29 are the only ones shown in use. To hold the cakes in position in the sockets, I utilize a frame 31 having fingers 32, which are adapted to bear against the cakes and hold them in. The frame is provided with a projection 33, which is adapted to enter a slot 34 in the end members 27 of the tray and to be firmly held thereby. The frame 31 and fingers 32 prevent the cakes from being pulled out of the sockets when the tray is withdrawn from the molten material.

To depress the tray-carriers 19 at the proper time, I employ a reciprocating element which comprises a cross-head 35, slidably mounted on studs 36 carried by the frame member 1. The studs 36 are crossconnected at the upper end thereof by a shelf 37 which is adapted to hold a tray. The cross-head 35 is provided with arms 38, the ends of which are provided with adjusting screws 39, which in turn bear against the tops of the tray-carriers 19, as shown. The adjusting screws 39 regulate and control the downward movement of the tray carriers 19, or, in other words, the screws 39 can be so adjusted as to cause the cakes 26 to be depressed into the material 11 to any desired 7 are provided with projections 46 against which the bar 45 will strike when pressed inwardly, as shown by dotted lines in Fig. 2. When the bar 45 is pressed inwardly, to aline with the projections 46, and the shaft 41 rotated, the receptacle 10 will be submerged in the molten material 11 and filled. This operation will take place, at intervals, when it becomes necessary to supply the receptacle 10 with fresh material. Normally the bar 45 will be kept out of alinement with the proj ection 46, by a spring 47, so that the said bar will not interfere with the operation of dipping the cakes. As the movement of the cross-head 35 will be intermittent and not constant, I loosely mount the pulley 44 on the shaft 41 and employ a clutch mechanism 48 (see Figs. 4 and 5) which is adapted to permit the shaft 41 to make one revolution only at a time. The clutch is controlled primarily by a lever 48 and secondarily by a lever 49 carried by a rotatable shaft 50, which in turn is rotated by a treadle 51 and counteracted by a spring 52 (see Fig. 1). The clutch mechanism comprises a sleeve 53, which is firmly keyed to the shaft 41. The sleeve 53 carries a rotatable stud 54, which at one end is cut away as at 55, leaving a semi-cylindrical projection 56. One end of the sleeve 53 is reduced, as at 57, and adapted to fit a counter-bore 58 in the hub 59 of the pulley 44. The counter-bore 58 of the hub 59 is counter-bored as at 60, the said counter-bore being of the same size as the projection 56 on the stud 54. While the lever 48 is held in the position shown in Fig. 4, the projection 56 will be held in the position shown, or in such a position as to keep the surface 61 in alinement with the surface of the counterbore 58 therefore the pulley 44 can freely revolve without revolving the shaft 41.

Should I desire to revolve the shaft 41, I depress the treadle 51 and cause the lever 49 to leave the lever 48 whereby spring 62 will tend to force the lever 48 outwardly, and when any one of the counter-bores 66 comes adjacent to the projection 56, the spring 62 will cause the lever 48 to fly outwardly, whereby the projection 56 will be revolved and lock the sleeve 53 and hub 59 together (see dotted lines Fig. 4). As soon as the cross-head 35 commences to descend, the foot is removed from the treadle 51 and the lever 49 is forced back to its normal position by the spring 52. VVhen the lever 48 comes in contact with the lever 49, after one revolution has been completed, it, the lever 48 will be forced to its normal position again; whereby the sleeve 53 and hub 59 will unlock. After each reciprocation of the cross-head 35, a new tray is substituted for the tray containing the articles dipped.

* The form of machine illustrated in Figs. 9 and 10 is the same as that illustrated in Figs. 1, 2 and 3, excepting that I employ a manually operated lever frame 63 to depress the tray-carriers 64, which are slidably mounted the same as the carriers 19. To depress, or submerge, the receptacle 65, I employ a crossbar 66 as shown. The tray-carriers are operated when the lever frame 63 is pressed downwardly. The tray-carriers and receptacle operating means are carried by a pivotal frame 67, mounted as shown. When I desire to refill the reservoir 68, or to clean it, I lift the frame 67 upwardly, at the free end, whereby the receptacle 65 andtray-carriers are lifted free of the reservoir. To refill, or clean, the reservoir 3 (Fig. 1), I slide the frame 14 to one side, to clear the arms 38, and then lift the free end of the said frame, whereby the receptacle 10 and tray-carriers are lifted free of the reservoir.

Fig. 8 illustrates a lattice tray having pins 69 to hold the cakes; the frame 31 is also used with this form of tray.
